Livestream: Watch Elon Musk at IAC2017 as he reveals Mars plan
Here’s how you can watch a livestream of Elon Musk at IAC2017
After many months of teasers from Elon Musk and SpaceX, Musk is about to give a presentation on SpaceX’s updated Big Falcon Rocket, which is expected to one day bring humans to Mars and potentially even support a city-sized colony on the planet.
Musk’s 2016 presentation on the Interplanetary Transport System captured the imaginations of many people, kindling the sort of excitement he has always hoped to inspire. Sitting in the audience during his Guadalajara, Mexico talk, his esoteric desire to make people excited to get out of bed in the morning resonated with me.
Updated: Elon Musk teases SpaceX-built cities on the Moon and Mars
Nevertheless, we now find ourselves almost exactly one year after his 2016 talk, and many things are believed to have changed with both SpaceX’s interplanetary colonization strategy and the hardware the company expects to develop to accomplish that colonization. Musk has said that tonight’s presentation will focus on the how of SpaceX’s Mars colonization efforts, entailing a somewhat smaller booster and spaceship with “major improvements”, as well as some “unexpected applications” for the vehicle.
Major improvements & some unexpected applications to be unveiled on Friday at @IAC2017 in Australia

What exactly those unexpected applications might be is fittingly unclear, if they are indeed less than obvious. More obvious applications for a fully-reusable heavy launch vehicle include
- More affordable access to orbit
- Mass launches of satellite constellations
- Off-the-shelf access to the surface of the Moon
- Space tourism in Earth orbit
- Cheaper and simpler space stations in a single launch
- Direct and rapid access to the Outer Solar System for more complex planetary exploration missions
These are just a handful of the potential uses and benefits that could be derived from a fully-reusable heavy launch vehicle like the Big Falcon Rocket (BFR). Unexpected or not, the near-Earth utility of a theoretical BFR is undeniable.

Aside from additional information on those unexpected applications, we can expect several exciting tidbits. Musk has teased new and improved videos of their Raptor rocket engine conducting live-fire tests, and we also have reason to believe that his talk will be accompanied by an equally slick and thrilling collection of renders of the updated BFR in action. Mirroring last year’s rather shocking unveiling of physical hardware development in the form of Raptor’s first test fire and a massive carbon fiber propellant tank, I personally expect to see confirmation of still more tangible hardware development.
A growing amount of recent news pointing to Boca Chica, Texas as the first launch site for SpaceX’s massive new rocket may also lead to an official statement from Musk himself either confirming or denying this, maybe accompanied by a tentative schedule for pad development. Regardless of what is revealed, tonight’s presentation is bound to be yet another exceptional opportunity to hear Musk wax poetic about SpaceX’s desire to make humanity a multiplanetary species.

Tesla Semi factory looks almost complete during Thanksgiving weekend
Based on recent drone videos, the Tesla Semi factory looks practically ready to start operations.
It appears that the Tesla Semi factory near Giga Nevada is already hard at work preparing for the initial production of the Class 8 all-electric truck. This was, at least, hinted at in a recent drone flyover of the facility from a longtime watcher.
The Tesla Semi factory after Thanksgiving
Drone operator and Tesla Semi advocate @HinrichsZane recently shared some footage he captured of the upcoming facility during the Thanksgiving weekend. Based on his video, it appears that Tesla gave its employees in the area the weekend off. One thing is evident from the video, however, and that is the fact that the Tesla Semi factory looks practically ready to start operations.
The Tesla Semi watcher did point out that the electric vehicle maker is still busy bringing in production equipment into the facility itself. Once these are installed, it would not be surprising if initial production of the Tesla Semi begins.
A new Tesla Semi
The upcoming completion of the Tesla Semi factory near Gigafactory Nevada seems all but inevitable in the coming months. What would be especially interesting, however, would be the vehicles that would be produced on the site. During Elon Musk’s presentation at the 2025 Annual Shareholder Meeting, a glimpse of the production Tesla Semi was shown, and it looks quite a bit different than the Class 8 all-electric truck’s classic appearance.
As could be seen in the graphic from the CEO’s presentation, the updated Tesla Semi will feature slim lightbar headlights similar to the new Tesla Model Y, Cybertruck, and the Cybercab. Tesla also teased a number of aerodynamic improvements that increased the truck’s efficiency to 1.7 kWh per mile. Extended camera units, seemingly for FSD, could also be seen in the graphic.

Tesla scores major hire as Apple scientist moves to Optimus team
Chen, who advanced from individual contributor to technical lead during his time at Apple, noted that he was blown away by Tesla’s efforts and synergy.
Former Apple research scientist Yilun Chen has left the tech giant to join Tesla’s Optimus AI team. Chen, who advanced from individual contributor to technical lead during his time at Apple, noted that he was blown away by Tesla’s efforts and synergy.
Apple veteran closes a major chapter
In a farewell note, Yilun Chen reflected on his tenure at Apple as a period defined by rapid growth and exposure to notable internal projects, some of which remain unreleased. His roles spanned engineering, research, early product incubation, and hands-on prototyping, allowing him to build expertise across both mature and emerging teams.
Chen credited mentors, colleagues, and cross-functional collaborators for shaping his trajectory, calling the experience unforgettable and emphasizing how each team taught him different lessons about scaling technology, guiding product vision, and navigating fast-moving research environments. “Each role has offered me invaluable unique lessons… My deepest gratitude goes to my colleagues, mentors and friends,” he wrote.
Tesla’s Optimus lab secured the hire
Chen said the move to Tesla was driven by the momentum surrounding Optimus, a humanoid robot powered by LLM-driven reasoning and Physical AI. After visiting Tesla’s Optimus lab, he admitted that he was “totally blown away by the scale and sophistication of the Optimus lab and deep dedication of people when I got to visit the office.”
His first week at Tesla, he noted, involved spontaneous deep-tech discussions, a flat team structure, rapid prototyping cycles, and what he called a “crazy ideas with super-fast iterations” culture. Chen emphasized that the team’s ambition, as well as its belief that humanoid robots are now within reach, creates an energy level that feels aimed at changing the world.

Elon Musk gives nod to SpaceX’s massive, previously impossible feat
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk gave a nod to one of SpaceX’s most underrated feats today. Following the successful launch of the Transporter-15 mission, SpaceX seamlessly landed another Falcon 9 booster on a droneship in the middle of the ocean.
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk celebrates a veteran Falcon 9 booster’s feat
SpaceX completed another major milestone for its Smallsat Rideshare program on Friday, successfully launching and deploying 140 spacecraft aboard a Falcon 9 from Vandenberg Space Force Base. The mission, known as Transporter-15, lifted off two days later than planned after a scrub attributed to a ground systems issue, according to SpaceFlight Now. SpaceX confirmed that all payloads designed to separate from the rocket were deployed as planned.
The Falcon 9 used for this flight was booster B1071, one of SpaceX’s most heavily flown rockets. With its 30th mission completed, it becomes the second booster in SpaceX’s fleet to reach that milestone. B1071’s manifest includes five National Reconnaissance Office missions, NASA’s SWOT satellite, and several previous rideshare deployments, among others. Elon Musk celebrated the milestone on X, writing “30 flights of the same rocket!” in his post.
Skeptics once dismissed reusability as unfeasible
While rocket landings are routine for SpaceX today, that was not always the case. Industry veterans previously questioned whether reusable rockets could ever achieve meaningful cost savings or operational reliability, often citing the Space Shuttle’s partial reusability as evidence of failure.
-->In 2016, Orbital ATK’s Ben Goldberg argued during a panel that even if rockets could be reusable, they do not make a lot of sense. He took issue with Elon Musk’s claims at the time, Ars Technica reported, particularly when the SpaceX founder stated that fuel costs account for just a fraction of launch costs.
Goldberg noted that at most, studies showed only a 30% cost reduction for low-Earth orbit missions by using a reusable rocket. “You’re not going to get 100-fold. These numbers aren’t going to change by an order of magnitude. They’re just not. That’s the state of where we are today,” he said.
Former NASA official Dan Dumbacher, who oversaw the Space Launch System, expressed similar doubts in 2014, implying that if NASA couldn’t make full reusability viable, private firms like SpaceX faced steep odds.
